Speaker



FIG. 1 is a front perspective view of a speaker.

FIG. 2 is a rear perspective view of the speaker shown in FIG. 1.

FIG. 3 is a front view of the speaker shown in FIG. 1.

FIG. 4 is a rear view of the speaker shown in FIG. 1.

FIG. 5 is a right side view of the speaker shown in FIG. 1, the left side view being substantially a mirror image thereof.

FIG. 6 is a top view of the speaker shown in FIG. 1; and,

FIG. 7 is a bottom view of the speaker shown in FIG. 1.

Any broken line showing of the environment is for illustrative purposes only and forms no part of the claimed design. The dash-dot broken lines which define the boundaries of the claimed design form no part thereof. The left side view is substantially a mirror image of the right side view and has therefore been omitted. 

CLAIM I claim the ornamental design for a speaker, as shown and described.
